[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-4 This utility model provides a washing device for graphite purification, including a filter box 1. A fixed frame 2 is slidably connected to the inner side of the filter box 1. An upper filter cloth 3 and a lower filter cloth 4 are fixedly connected to the upper and lower ends of the inner side of the fixed frame 2, respectively. Supports 5 are fixedly connected to both sides of the top of the fixed frame 2. The top ends of the two supports 5 abut against the two ends of the top of the filter box 1, respectively. A washing box 6 for graphite purification is fixedly connected to one side of the filter box 1. A spiral feeding disc 7 is rotatably connected to the inner side of the washing box 6. An inclined feeding pipe is fixedly connected to the bottom of the washing box 6 at the end away from the filter box 1. 9. The other end of the feed pipe 9 is fixedly connected to the drying box 10. The filter box 1 is provided with a feed trough 20 at the end near the washing box 6. The end of the lower filter cloth 4 near the washing box 6 is inclined downward. The feed trough 20 is located between the upper filter cloth 3 and the lower filter cloth 4. The top of the inner side of the washing box 6 is fixedly connected to the spray seat 8. The top of the spray seat 8 is fixedly connected to the input pipe, and its top end passes through the washing box 6. The side of the washing box 6 away from the filter box 1 is fixedly connected to the motor, which is model Y132M-4. Its output end passes through the inside of the washing box 6 and is fixedly connected to the spiral feed disc 7.

[0026] Spherical graphite raw material is poured into filter box 1. Solid impurities are separated by upper filter cloth 3, and liquid impurities are separated by lower filter cloth 4. The graphite raw material slides along the inclined surface above the lower filter cloth 4 and passes through the feed trough 20 into washing box 6. The spiral feed disc 7 driven by the motor continuously turns the graphite raw material and pushes it into drying box 10. The input pipe is connected to an external quantitative liquid supply device, and a quantitative washing liquid is input into the spray seat 8. The external quantitative liquid supply device is existing technology. The spray seat 8 sprays the washing liquid to wash the graphite. The washed graphite moves to the discharge pipe 9 and slides into drying box 10.

[0027] Because the pore size of the upper filter cloth 3 is larger than that of the spherical graphite raw material, it is mainly used to intercept larger particles of impurities in the graphite. Its material is cotton fiber. The pore size of the lower filter cloth 4 is smaller than that of the spherical graphite raw material, so it is used to filter out liquid components mixed in the graphite. Its material is polyester. This double-layer filter cloth design allows the graphite to remove large particles of impurities and excess liquid at the same time when it passes through the filter box 1, ensuring that the graphite entering the subsequent washing stage is purer, thereby improving the effect of the entire washing process. The lower filter cloth 4 adopts an inclined design, which allows the graphite to slide automatically into the washing box 6 along the inclined surface of the lower filter cloth 4 by its own gravity. This gravity-based feeding method not only reduces manual intervention and improves feeding efficiency, but also avoids graphite damage or secondary pollution that may be caused by mechanical conveying. The bracket 5 allows the fixing frame 2 to be disassembled and assembled, which facilitates quick disassembly and assembly of the upper filter cloth 3 and the lower filter cloth 4, and extends the service life of the device.

[0028] Please see Figures 1-4 A first cylinder 11 is fixedly connected to the top of the drying box 10. The bottom end of the first cylinder 11 extends into the interior of the drying box 10 and is fixedly connected to a top seat 12. A pressure plate 13 is fixedly connected to the bottom of the top seat 12. The bottom end of the pressure plate 13 is a protruding cylindrical shape. An electric heating ring is fixedly connected to the inner side of the bottom end of the pressure plate 13. A support plate 17 is slidably connected to the bottom of the inner side of the drying box 10. A second cylinder 14 is fixedly connected to the top of the inner side of the top seat 12. A connecting frame 15 is fixedly connected to the bottom of the second cylinder 14. Several push plates 16 are fixedly connected to the bottom of the connecting frame 15. The push plates 16 are slidably connected to the inner side of the pressure plate 13. There are three push plates 16, which are distributed in a ring on the inner side of the pressure plate 13. A movable door 18 is hinged to the side of the drying box 10 away from the washing box 6. A screen 19 is fixedly connected to the bottom of the drying box 10.

[0029] When cylinder 11 operates, it drives the pressure plate 13 to move downward, squeezing the graphite and causing the liquid inside to be discharged from the screen 19 into the drying chamber 10. Then, the graphite is dried by the heating ring inside the pressure plate 13. After drying, the pressure plate 13 is driven to rise. When cylinder 14 operates, it drives the push plate 16 to move downward through the connecting frame 15, and the graphite adheres to the pressure plate 13. Then, the movable door 18 is opened, and the graphite is pulled out through the support plate 17.

[0030] Driven by cylinder 11, the pressure plate 13 moves downward, applying pressure to the graphite inside the drying chamber 10. This fully squeezes out the residual liquid inside the graphite and discharges it through the screen 19, which is a graphene composite material screen plate that can filter out the water in the graphite, thus achieving efficient solid-liquid separation. At the same time, the electric heating ring inside the bottom of the pressure plate 13 can evenly heat and dry the graphite, ensuring that the graphite can quickly remove moisture while under pressure, achieving the ideal drying effect. The pusher plate 16 is distributed in a ring, which can push the graphite in all directions, avoiding the graphite from remaining on the pressure plate 13 due to adhesion after drying. After the graphite is dried, it can be smoothly moved out of the drying chamber 10 through the support plate 17. The entire process does not require external equipment. The device itself can complete the entire process of solid-liquid separation, drying, and unloading. This integrated design not only simplifies the operation process and reduces equipment costs, but also greatly improves the practicality and working efficiency of the device.

[0031] The working principle and usage process of this utility model are as follows: Graphite raw material is poured into the filter box 1. Large solid impurities in the graphite raw material are separated by the upper filter cloth 3, and liquid impurities are separated by the lower filter cloth 4. The graphite raw material slides along the inclined surface above the lower filter cloth 4 and passes through the feed trough 20 into the washing box 6. The spiral feed disc 7 driven by the motor continuously turns the graphite raw material and pushes it towards the drying box 10. Washing liquid is input into the spray nozzle 8 through the input pipe and sprayed out to clean the graphite. After washing, the graphite moves to the discharge pipe 9 and slides into the drying chamber 10. The first cylinder 11 works, driving the pressure plate 13 to move downward, squeezing the graphite so that the liquid inside it is discharged from the screen 19 into the drying chamber 10. Then, the graphite is dried by the electric heating ring on the inner side of the pressure plate 13. After drying, the pressure plate 13 is driven to rise, and the second cylinder 14 works, driving the push plate 16 to move downward through the connecting frame 15. The graphite adheres to the pressure plate 13. Then, the movable door 18 is opened, and the graphite is pulled out through the tray 17.
